Marilyn Berenzweig was a successful New York textile designer who loved her work and comfortable lifestyle. For the past year, however, she and her husband have been living in a tent city in the New Jersey woods.

"The weather, the bugs, the dirt; I think it's the dirt that really gets to me," she said. "It's not like you can pop in the shower at the end of the day.

"It's life on a much more primitive level. ... Cooking on a wood stove ... having no running water, no electricity."

Berenzweig, 60, and husband Michael live at Tent City Lakewood, a growing community of 70 homeless people living in a series of tents, shacks, trailers and tepees in a wooded area along the Jersey Shore about 25 miles north of Atlantic City.

When they first lost their home, they tried living with their daughter, son-in-law and three grandchildren.

"It didn't work out ... too many clashes of temperament," she said.

Their son-in-law drove them to the camp 16 months ago. Other than telling their daughter, they've kept their whereabouts off Ocean County Parkway a secret from family members.

"A friend of ours had mentioned tent camps earlier, thinking it was disgraceful what this country came to with economics being so bad at the time," she said.

She never imagined she'd soon be living in one.

Berenzweig and her husband's makeshift home is a wood-framed shack covered with a tarp and blankets. They've created a patio of sorts with blue tarp hanging over a series of plastic chairs and tables. Underneath the tarp are signs of everyday life: a propane fueled stove, dishes, a dictionary, cooking utensils, a coffee mug.

Their patch of land has a chicken coop on it and a wood stove to be used during the harsh winters to stay warm. A shopping cart is full of wood and paper to be burned in the stove.

They brought their cat and birds to live with them, remnants of the life they once had. They've adjusted to being labeled homeless, but some parts of having nothing are more difficult to handle.

"It's kind of hard to take things. It's hard to be an object of charity," she said. "That takes some getting used to."

Berenzweig's circumstances aren't unique. The rocky economic recovery and stagnant unemployment rate have led to a surge in the homeless seeking shelter in shanties and tents nationwide, experts say.

The modern-day Hoovervilles have names such as Dignity Village or Pinellas Hope or simply Tent City 1. There's no official estimate on how many tent cities exist but, experts say, nearly every state has one and the presence of such communities is soaring.

"In just about every major city, there are tent cities," said Michael Stoop, a community organizer for the National Coalition for the Homeless. "Unfortunately, we're in a growth industry and the numbers are going to continue."

Stoop and his organization began formally tracking tent cities in 2010 but the numbers have grown so much that trying to keep a detailed report of every tent city has overwhelmed them.

"Imagine if you had never been homeless before and you'd just lost your job and you lost your home," he said. "What would you do? Would you immediately go begging or knocking on a door?

"No, you would downsize, move into cheaper accommodations, if that did not work you'd move in with friends or relatives and then you'd move into a cheap motel and then ... where would you want to go before winding up at a shelter door? You would much prefer to live at a park with your family and your dog," he said.

The communities range from just a few people living together in tents or wooden shelters to full-fledged organized communities such as the one in Lakewood. Just a few homeless people began gathering in the woods there in 2005, but as the financial meltdown worsened, their numbers grew.

Steve Brigham, a pastor, has been working with the community since it began forming. Two years ago, he quit his job as an electrical contractor and now lives with the homeless in the camp. He lives in a bus donated to him from a local school.

"I wonder to myself how long I can continue with the population growing, resources dwindling. ... I'm very concerned about this winter, extremely concerned about ... whether I'm going to have everything I need to keep these people satisfied and comfortable and the basic needs met," Brigham said.

'Township Should Be Proud' of Tent City

Brigham helps welcome and support newcomers. He supports the community as a whole, seeking donations and services for the needy. He also is the pastor of the tent's chapel, a wood structure that he built.

New Jersey, as with much of the nation, has no right to shelter. For the past year, Tent City Lakewood has been fighting a lawsuit filed by the township and county to evict them from the woods. As part of the pending litigation, Brigham and the community have to take down the chapel and 14 other structures at the camp by next week.

"For somebody to say that you've got to tear down the housing that's going to keep them warm and they don't offer an alternative or an option, it's extremely disheartening," Brigham said.

Lakewood and Ocean County officials did not respond to requests for comment from ABCNews.com.

Jean Cipriani, a lawyer for the Ocean County Board of Social Services, told NorthJersey.com, "There is a difference between the government's authority to provide services and their obligation to do so. There are many things that the government must do, but this is not one of them."

Jeffrey Wild and his law firm, Lowenstein Sandler, have been working pro bono to help the community counter the lawsuit. They're fighting for a shelter or affordable housing to be built for those living in the tent city.

"Me and my law firm ... are trying to fight for the right of the people in this tent city and everyone in New Jersey to have a right to shelter when you have nowhere else to go," Wild said. "The court case was brought by Lakewood seeking to forcibly eject everybody living here, even though it is public land."

Experts say that local and state governments are often ill equipped to handle tent cities.

"Most cities aren't really set up to deal with tent camps, in terms of sanitation, clean water, fire and police services, and so there's a lot of pressure on them to shut them down," said Tim Iglesias, a professor at the University of San Francisco who focuses on housing law. "Also, most cities have housing codes, which define what constitutes a habitable dwelling for a human being and tent camps rarely are going to meet that standard or that qualification."

On top of the legal violations, the tent cities make poverty uncomfortably visible to some members of the public, raising fears, sometimes unfounded, about depreciating home values and crime.

"There's the, 'not-in-my-backyard phenomenon,' no one likes to acknowledge that homelessness is a big issue," attorney Wild said.

Berenzweig said the community complained when Berenzweig and her husband first moved to Tent City Lakewood, which is difficult to see from the parkway.

"When we came here, they [Lakewood residents] immediately complained about us in particular," she said. "We were too close to the road and motorists might see us. In other words, to have to see homeless people when you're driving your car is like some horrible thing. It's always something."

Berenzweig said she thinks the tent city should be a source of pride for Ocean County, which has no homeless shelter.

"I would like to see it remain," she said. "I think it fills a need. ... Everybody seems to blend and mesh together pretty well. I think the township should be proud and be helping and be contributing."
